I went with him to build the Keystone
Zinc Compa orks at Birmingham,
Pennsylvania. I think he left the Birmingh ks and
went to Bayonne, New Je remaining as

wards professor of chemistry at the State School of Mines,
Rolla, Missouri, was employed as chemist :o assist me, or
direct me, and he would spend about two days of each
month at Birmingham. The bah the tim( - in

lead by the same process used to make white zinc — sublime

the question to Mr. Williams. His answer
was that it was impossible. I suppose
that I am of an inquiring mind, at
, least I asked him why it was impos-
KMi$ sible. He turned around to me
r and said, " You're a fool." That
^ped all talk between him and me
ret. Of course I went on and
although I had some trouble.

I found that he said it would be possible to
and gases from lead fumes by using some kind
>ric as a strainer, if it was not for the heat and
: acid. If Mr. Williams had explained to me
impossible >uld not be asking me to

lint that has no equal,

aint but will not stand hard
checking, it being so hard and brittle. Sublimed White
Lead has the good qualities of zinc, being made with fire,
and the good qualities of carbonate of lead, without any
of the bad qualities of either.
C. After years of exposure a paint film of Sublimed White
Lead remains white, firm and solid, and presents an excellent
surface for repainting. No special preparation of the sur-
face is necessary, and the old paint film will take and hold
a new coat to the satisfaction of the most exacting painters.

to vaporize the lead contents with sufficient access of air to
oxidize it into a basic sulphate compound of lead.

through a long series of sheet iron pipes cr flues, up around

winding flues for a distance of pra one thousand
feet, until it is finally caught and retained in the fabric
strainers (bags), it will be realized that the pigment par-
ticles must be in a fine state of subdivision. As a matter of
fact these ultimate particles of drv Sublimed White Lead are
so fine as to be practically formless — perfectly amorphous.
Many pigments, especially those torn

be borne in mind when designing
a ready mixed paint. Whatever the

and to substitute for the fragility of lead carbonate, with its
tendency to "go dead," to "check" and "chalk," the
stable unchanging solidity of Sublimed White Lead. This
pigment in combination with zinc alone, or with zinc and
corroded lead would seem to make attainable the highest
possible type of ready mixed paint, in which the known
virtues of each would be utilized to the fullest extent, while
the inherent defects of each are fully corrected by the
others. The practical experience of the leading paint
manufacturers has completely established the truth of this
deduction.
